Dryer Repair

The dryer portion of the COMBO is a condenser type dryer. It works on
the principal that water condenses on a cool surface, similar to moisture
collecting on a cold drink on a hot and humid summer day. A fan
circulates air through the warming duct, drum, and condenser and over
and over. The air is warmed because warmer air holds more moisture
than cooler air and the heat causes more of the water to be evaporated
from the laundry. The warm, moist air is directed through the
condensing duct, which is cooled by a stream of cold water. This
difference in temperature causes the moisture to precipitate in the
condenser, where it and the cooling water are exhausted by the drain
pump. The air, now dry, is passed over the warming element and
through the laundry again as the process repeats itself. Because the air
is recycled instead of exhausted, a vent and lint filter are not necessary
for this type dryer.
NOTE: The Cooling Water rinses any Lint from the DUCT
Lint may accumulate in the Hose between the DUCT and PUMP
